已安装但未安装RHEL6

Question

我在试着解决一个依赖。因为RHEL6不包含python-2.4.3，所以我从RHEL5下载了这个包，并将其放入我们自己的存储库中。然后在安装后：

我该怎么解决这个问题？

Answer 1

解决方案是为RHEL 6重新构建您的专有包，以便它使用RHEL 6附带的Python版本(和其他依赖项)。试图迫使它使用旧的Python版本并不是正确的方法。

Answer 2

您可以根据当前的CentOS 6设置，从源代码创建自己的RPM。

关于如何做到这一点的简单答案是

rpmbuild --rebuild /tmp/mypythonpackagename-2.3.4-56.src.rpm

有关详细信息，请参阅http://wiki.centos.org/HowTos/RebuildSRPM

Answer 3

您正在尝试安装一个较旧的python版本，以取代较新的版本。由于yum依赖于python，这不是一个好主意。

使用像这一个这样的存储库，并行地安装旧的python版本。
